LAMP.

SPECIFICATION forming part of Letters Patent No. 439,995, dated November 4, 1890.

Application filed February'l3, 1890. Serial No. 340.309. (No model.)

To all whom it 11mg concern.-

Be it known that I, WILLIs BENNER, of New York city, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 shows a perspective view of my improved lamp; Fig. 2, a View of a vertical section on line 00 m of Fig. 1; Fig. 3, a detail perspective view showing the catch for looking the handle attached to the rock-shaft; Fig. at, a perspective view showing the casing top carrying the chimney and shade-supports raised from the casing and lamp-body as when the latter is to be lifted from the casing; Fig.6, a detail perspective view showing a portion of the removable casing-top provided with a flange to fit within the upper end of the casing; Fig. 6, a detail view, in side elevation, of a modified form of means for raising and lowering the lamp-body; and Fig. 7, a transverse vertical section showing the manner of applying my invention to a lamp having a difierent form of easing from that shown in Figs. 1 and 2.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide an improved lamp; and to this end my invention consists in the lamp and in the construction,

arrangement, and combination of the parts thereof, as hereinafter specified.

While I have shown and shall describe my invention as applied to the well-known Rochester lamp, I desire it to be understood that my invention or parts thereof can be equally well applied to or used in connection with other kinds of lamps.

In my United States patent, No. 407,153, I show and describe a lamp in which the movable lamp-body is arranged within a casing which has a door in its side through which the said body when lowered can be removed.

In the present case my invention is shown as applied to a lamp in which the casing is without the side door, and the lamp-body is to be made removable through the top or upper end of the casing. This arrangement is found desirable in so me forms of lamps where the configuration or ornamentation of the easing will not admit of the presence of a door in the casing side.

With the lamp arranged as shown and de scribed in the present application it will be seen that the exterior casing can be made more symmetrical, is capable of better ornamentation, and can be more varied in its shape or configuration than the casing shown on my patented lamp.

In the drawings, A designates the exterior casing, which, while shown in Fig. 1 as substantially cylindrical, can be varied indefinitely in shape, as desired, without departure from-my invention. It can also be made of any suitable material. While it appears in Fig. 1 as a closed sided cylinder, such a constructionis not necessary. For the sake of ornamentation or to secure lightness portions of the casing can be cut away or removed to any desired extent, provided, however, that enough of the casing material is left to properly support the parts of the lamp and guide and steady the movable lamp-body B. Such body is, like that shown in my said patent, made movable up and down within the casing A, and carries with it the burner B, which has the general appearance and construction of that on the well-known Rochester lamp, except in one essential particular. 1

Instead of having the annular chimney:

holder or support 0 fastened to or made in one piece with the perforated cylinder 1), which surrounds the wick-tube E, I separate the chimney-holder from such cylinder, so

that the burner can move with the lamp-body as the latter is raised and lowered, while the chimneyholder remains stationary. Such holder 0 is of the ordinary shape, and consists of a ring having the upwardly extending flange 0' around its inner edge and the up right spring-fingers (3 G C for receiving and embracing the base of the chimney F. I do not, however, desire to limit myself to such construction.

For supporting the ring from the casing A, I provide several upwardly and inwardly extending arms G G, having their upper ends attached to said ring and their outer and lower ends connected with a piece H, which rests upon the top of easing A. For steadying and holding this piece H in place I provide it either with arms H H H or with a flange (see Fig. 5) adapted to project down within, or, as indicated in dotted lines in Fig. 4, out-side of the casing.

Instead of having the upwardly-extending arms G G G for carrying the annular chimney-holder C, I contemplate, where it is desired, forming the piece H with an upwardlyextending hood, as indicated in dotted lines in Figs. 2 and 3, which would hide the top of the lamp-body, and to the upper end of which the ring forming the chimney-holder would be attached. An opening or openings could be made in such hood to admit the passage of the usual Wick-raising arm I when the lamp-body was raised and of a match or lighter to light the lamp. On the upper end of the perforated cylinder D, surrounding the wick-tube of the burner, is an annular flange or collar d, which, when the lampbody is raised, projects up Within the chimney-holder C. The same steadying and guiding connection between the burner and the chimneyholder can obviously be obtained by inverting the arrangement described and providing the holder itself with a flange or collar to engage the inner or outer side of the upper end of the perforated cylinder.

The shade-receiver K shown is of the ordinary and well-known form, with a ring to engage and be held by the chin] hey-support, and the usual radiating arms K K K. It can be so made as to be detachable from the chimney-holder, or, if desired, the arms K K K can be rigidly secured to such holder or be formed of continuations of the arms H H H. Either of the constructions described can be used without departure from my invention.

For the purpose of guiding the lamp-body as it is moved up and down and steadying it in place when it is raised, guides L L L to engage the inner wall of the casing A are formed on or attached to the body sides.

For raising and lowering the lamp-body I make use of a device similar in some respects to the one used in my lamp shown and described in my said patentthat is, I still have the rock-shaft M with an arm M there on, while the means for securing the locking of the shaft when it has been turned to raise the lamp-body is quite different from that shown in the patented lamp. I now pivot or journal the shaft in the casing or on some support, so that it will be capable of a longitudinal as well as rocking movement. At one end it projects out through the casing, and is provided with a head or handle N by which it can be rotated.

In the form of lamp shown in Figs. 1, 2, and 3 one of the handles for lifting and carrying the lamp is attached to the shaft end and utilized as the means for turning and securing the locking of the shaft. On the lampcasing A is a notched lug 0, having its notch 0 so arranged that a portion of the handle N will engage the same when the shaft has been turned to bring the arm M and the attached handle upright and has then been moved longitudinally inward. Around the shaft, within the casing A, is a spiral spring P, which, pressing at one end against the casing and at the other engaging the arm M, tends to force the shaft longitudinally inward and hold it as so moved. The side of lug O, which the handle N first strikes as it is turned upward, is provided with an inclined surface 0, as shown, over which the engaging part of the handle rides until it reaches the notch 0. On the further side of such notch the lug has a projecting arm 0 which acts as a stop to limit the movement of the handle and prevent its being swung too far over past the notch. With the construction shown and described the handle attached to the shaft will, because of the foreing inward of the latter by the spring P, be held securely in engagement with its lockingnotch until it is grasped and drawn outward against the stress of the spring.

In Fig. 6 is shown a modification of my lamp-body moving and locking mechanism, in which, instead of having the arm M engage the lamp-body directly, I connect pivotally with such arm acon'necting-rod R, which at its upper end is adapted to engage the bottom of the lamp-body. Such rod can be guided in its movements by a suitable guiding-opening S in a cross-bar or piece S, attached to the lamp-casing, and can have its upper end provided with a head or crosspiece R to engage the bottom of the lampbody. The outer end of the shaft is shown as provided with a suitable turning-head, which, like handle N on the shaft in theform of lamp hereinbefore described, has a lug or portion to engage a locking-notch 0 when the shaft has been rotated to cause raising of the lamp-body, and then moved longitudinally inward by the stress of the spring P.

The modification just described is for use particularly where the casing is a long one, or for some reason it is preferable or necessary that the shaft M be placed at some distance below the lamp-body.

In Fig. 7 I show the manner of applying my invention to a lamp having a casing which is not cylindrical in general form. To provide means for guiding and steadying the lamp-body, the interior of the casing is then provided with an inner piece T, adapted to be engaged by the lam p-body or guides thereon. Such piece can consist of a cylinder surrounding the lamp-body and engaging vertical guide-ribs on the outer side of the latter; or without departure from my invention the casing or the inner cylinder can be provided within with several guide-arms to engage the lamp-body directly.

The operation or manner of using my lamp, as hereinbefore described and shown in the drawings, is briefly as follows: When the lamp is to be lighted, the handle or head on IIO the shaft M is drawn outward against the stress of spring P, and having been disengaged from the holding-notch is turned so as to rotate the shaft and swing the arm M thereon downward. By the descent of this arm the lamp-body is lowered within the casing, so that the burner can be readily reached for lighting Without the necessity of any removing or touching of the chimney-holder, chimney, or shade. WVhen the lamp is lighted, there is no danger of smoking the chimney,

even if the lamp-body be left down for a lamp-body B to its elevated position again,

with the collar or flange d on the perforated cylinder D of the burner projecting up within the chimney-holder and fitting Within the latter, so that the air reaching the burner from outside the wick-tube must pass, as is desirable in the form of burner used through the perforations in said cylinder D. As the arm M is brought by the rotation of the shaft M into its upright position, the notchengaging portion of the head or handle N rides over the incline 0 on the ing 0, so as to force the shaft longitudinally outward against the stress of the spring, and then after it leaves such incline it is at once carried into the locking-notch 0 by the spring drawing the shaft inward again. If it is desired to remove the lamp-body from the casingas for filling, emptying, or cleaning itthe piece H, carrying or supporting the chimney-holder and shade-support, can be readily lifted from the casing and set to one side Without the necessity of anyhandling or disturbing of the chimney or shade. When the lamp-body is put back within the casing, the piece H can be readily set in place on the casing-top and the lamp will be immediately ready for use.

My arrangement and construction 'of lamps whereby all handling or touching of the chim ney and shade is rendered unnecessary when the burner is to be lighted or the wick trimmed have been found to be very advantageous, as preventing all danger of smoking, soiling, or breaking the chimney, or of injury to the shade consequent upon the removal and replacing of the latter, necessary in the ordinary form of lamp, whenever it is to be lighted or trimmed.

As indicated hereinbefore, the arrangement of my lamp, whereby the lamp-body can be removed through the top of the casing instead of through a side door, is advantageous,in that it allows the lamp to be made more symmetrical and the lam p-casing to be varied in shape indefinitely and ornamented as extensively as may be desired.

Where the lamp-body used has a burner without the perforated cylinder D surrounding the wick-tube, the chimney-holding ring can, where such is desirable, be provided with a perforated annular piece, as indicated by dotted lines in Fig. 4, up within which the wick-tube will project when the lamp-body is raised. I prefer, however, the perforated cylinder arranged as described and shown hereinbefore, as it is more convenient, and with it there is no danger of smoking the chimney or chimney-holder when the lamp-body is down and the wick is being lighted, as there is Where a perforated inner ring on the chimneyholder is used.

WVhile I show and describe the flange or collar on the upper end of the perforated cylinder D, I do not consider the same necessary to secure a good working of the parts of the lamp. It can be dispensed with and the cylinder end can be simply arranged to abut against or be flush with partof the chimneyholder ring.
